Purpose To evaluate the effect of the coronavirus disease 2019 (COVID-19)-related lockdown in the management of patients with diabetic retinopathy (DR), including diabetic macular edema (DME), in a tertiary reference center in Greece. Methods In this retrospective study, we first compared the number of patients who were diagnosed with DR or DME in our clinic during the period of the lockdown and during the same period of the previous year. In addition, we included consecutive patients with DR or DME, who were followed up and treated regularly in our clinic and their appointments deferred due to lockdown, so as to compare the visual acuity, fundoscopy, and optical coherence tomography (OCT) findings prior to and post lockdown. Results During the lockdown period, there was a statistically significant decrease in patients with DR and DME as compared to the same period in the previous year. Regarding patients with previously diagnosed DME, there was a statistically significant worsening in their visual acuity and central retinal thickness after lockdown as compared to the last visit before lockdown (p

PURPOSE To study the evolution of idiopathic epiretinal membrane (IERM) as examined by optical coherence tomography (OCT) in the 1-mm-diameter circle centered on the fovea. METHODS In a case series study 71 subjects (71 eyes) with idiopathic epiretinal membrane and macular thickness greater than 220-/+10 micro m were evaluated by OCT. The fellow healthy eye of 52 patients was used as the control group. The mean follow-up was 36 months. Measurements of macular thickness at baseline and at the final examination were performed. Best-corrected visual acuity was expressed as the number of letters read on the Early Treatment Diabetic Retinopathy Study chart. RESULTS Within the inner macular central circle of 1 mm diameter the thickness of the fovea increased by an average of 12.29% (p

PURPOSE. To report in a single case the effectiveness of bevacizumab in the treatment of feeder vessels (FVs) of subfoveal choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD). METHODS. One patient received intravitreal bevacizumab (Avastin) (1.25 mg) which was repeated 4 weeks after the first intravitreal injection. Fluorescein angiography and optical coherence tomography (OCT) were performed. Visual acuity (VA) was also checked. RESULTS. Occlusion of the FVs was observed 4 weeks after starting treatment. During the follow-up period and in the final examination 13 months after the first injection, the FVs remained occluded. Complete resolution of macular edema and improvement of the VA were noticed after the second bevacizumab intravitreal injection. CONCLUSIONS. This report documents the successful occlusion of FVs of subfoveal neovascularization after two intravitreal bevacizumab injections in a patient who was followed up for 1 year after the occlusion. Further long-term investigation is warranted given the promising 12-month results. (Eur J Ophthalmol 2007; 17: 853-6) K EY WORDS.

PURPOSE. To report a case of pigment epithelium detachment (PED) which appeared after photodynamic therapy (PDT) and was followed up for 50 months. METHODS. Case report. RESULTS. A 71-year-old woman with occult choroidal neovascular membrane due to age-related macular degeneration (ARMD) developed PED 48 hours after PDT. The patient was studied with fluorescein angiography (FA) and optical coherence tomography (OCT). Fluorescein angiographic evidence of PED remained essentially unchanged during the follow-up period of 50 months. Although OCT initially gave clear evidence of PED, in the last 12 months of follow-up the PED appears to have resolved. CONCLUSIONS. Photodynamic treatment could be involved in the occurrence of PED in occult choroidal neovascular membrane due to ARMD. In this particular case OCT could be considered since it offers useful information in the pretreatment and the post-treatment follow-up period.

A case of bilateral “drusenoid” pigment epithelial detachment that was studied with fundus fluorescein angiography and optical coherence tomography is described. Fundus fluorescein anglography depicted staining of the drusen without any sign of pooling of the dye, whereas optical coherence tomography displayed detachment of the retinal pigment epithelium. These findings remained unchanged during a 10-month period.

A 35-year-old man was observed during a 21-year period with fundus color photography, fluorescein angiography, and B-scan ultrasonography for a presumed retinoma detected in his left eye during routine ophthalmoscopy in 1982. The patient was a carrier of the 13q14 retinoblastoma gene. His retinal lesion remained stable during the follow-up period without signs of malignant transformation. Retinomas are most commonly observed in patients with retinoblastoma and their relatives. In this case, none of the patient’s parents, siblings, or children had evidence of a retinal tumor. Photographic documentation of the nonprogressive nature of this presumed retinoma is provided and demonstrates the absence of growth.

Purpose: We sought to investigate contrast sensitivity on the fellow eyes of amblyopic and successfully treated amblyopic subjects. Methods. Contrast sensitivity was tested monocularly on both eyes of 48 amblyopic patients (mean age, 11.51 years) and of 22 successfully treated amblyopic subjects (visual acuity 20/20 in each eye; mean age, 11.22 years). Inclusion criteria were visual acuity in the amblyopic eye 20/40 or better (mild amblyopia) and 20/20 or better in the fellow eye, steady fixation, no signs of congenital, latent or manifest/latent nystagmus on clinical examination. Twenty normal subjects (20 eyes) were used as age-matched controls. Results: Contrast sensitivity functions from the fellow eye of the 48 amblyopic patients, even those who had never been treated with occlusion therapy before, were significantly decreased (P < 0.001) compared with control subjects. Both the previously amblyopic and the fellow eye of the 22 “cured” amblyopic subjects demonstrated significantly lower values (P < 0.001) compared with control patients. Conclusions. We suggest that the nonamblyopic, “normal” eye of amblyopic patients behaves abnormally when evaluated for contrast sensitivity functions. Neither the previously amblyopic nor the fellow eyes of successfully treated subjects were comparable with controls. Occlusion therapy may not be implicated for depressed contrast sensitivity of the fellow eye in amblyopia. The assessment of contrast sensitivity can provide important information on the visual function and the influence of occlusion therapy in amblyopia.

PURPOSE: To assess the efficacy of the anti-TNF monoclonal antibody infliximab in uveitis patients without clinically evident ocular inflammation and impaired visual acuity because of chronic cystoid macular edema (CME). DESIGN: Prospective, noncomparative, interventional case series. METHODS: Patients with refractory CME (14 eyes, mean duration of 14 months), associated with intermediate uveitis (n = 6), Adamantiades-Behcet disease (n = 2), adult-type vascular pseudotumor (n = 1), and HLAB27+-related uveitis (n = 1) received an intravenous infliximab infusion (5 mg/kg); five patients were retreated after 1 month. RESULTS: Macular thickness, measured by ocular coherence tomography, was reduced from 428 +/- 138 mum to 219 +/- 51 mum at 2 months postbaseline (P = .0001), while visual acuity increased from 0.41 +/- 0.18 to 0.83 +/- 0.17 (P < .00001). Anatomic and functional improvement was sustained at 6 months in all. No ocular or extra-ocular side effects were noted. CONCLUSION: These promising results suggest that TNF may play an important pathogenetic role in chronic CME, thus, a controlled trial is warranted. (C) 2004 by Elsevier Inc. All rights reserved.

Purpose: To present the postoperative optical coherence tomography (OCT) findings of the macula in rhegmatogenous retinal detachment with spared macula preoperatively. Methods: Eleven of 46 patients who underwent surgery for rhegmatogenous retinal detachment had an uninvolved macula preoperatively. Scleral buckling without intravitreous gas injection was the operation used in all eyes. All 11 patients were examined before and after treatment with slit-lamp biomicroscopy, indirect ophthalmoscopy, fundus photography, fluorescein angiography, and OCT. Results: In 3 of the 11 patients with rhegmatogenous retinal detachment and uninvolved macula preoperatively, fluid was identified with OCT in the macula after successful treatment. OCT showed that the fluid gradually diminished and finally disappeared 5 to 7 months after the scleral buckling procedure. The fluid in the macula became visible with slit-lamp biomicroscopy in only one of the three patients. Conclusion: Subretinal fluid in a preoperatively uninvolved macula can be found after successful treatment of rhegmatogenous retinal detachment. If the fluid is located in the fovea, the visual acuity decreases and does not reach the preoperative levels. OCT identifies the presence of fluid and contributes to the study of the fluid’s evolution.

PURPOSE. To evaluate by multifocal electroretinogram (MF-ERG) macular function before and after photodynamic therapy (PDT) in myopic eyes with choroidal neovascularization (CNV). PATIENTS AND METHODS. Ten eyes with classic subfoveal CNV due to pathologic myopia were studied with MF-ERG before and after PDT in order to evaluate the results of PDT with verteporfin. The post-treatment follow-up was 6 months. Visual acuity testing, ophthalmic examinations, fluorescein and indocyanine green angiograms, and MF-ERG recordings were used to evaluate the results of PDT with verteporfin. The post-treatment period was 6 months. RESULTS. Before treatment, the electrical response densities in the foveal and perifoveal areas were apparently decreased in all patients. Six months after treatment, the mean retinal response densities in the same areas were found to be higher than before treatment. CONCLUSIONS. MF-ERG evaluates objectively the macular function in myopic eyes with CNV After successful PDT, the electrical activity of the foveal and parafoveal areas is higher than before treatment. This finding postulates the efficacy of PDT in the treatment of CNV.

PURPOSE: To evaluate successful macular hole surgery using optical coherence tomography (OCT) and multifocal electroretinography (MFERG). . DESIGN: Interventional case series. .METHODS: In a prospective study, 20 eyes of 20 patients with successful surgery for stage II, III, or IV idiopathic macular hole were evaluated by best corrected visual acuity (BCVA), ocular examination, OCT, and MFERG preoperatively and 1, 3, 6, and 12 months postoperatively. For statistical analysis, the paired t test and nonparametric methods were used, as well as the Spearman analysis. . RESULTS: Postoperatively, all 20 eyes of 20 patients had anatomic closure of the macular hole confirmed by OCT. The center of the fovea, measured by OCT from the retinal pigment epithelium to the inner retinal surd face, had a mean +/- SD thickness of 116.5 +/- 30.9 mum (range, 68-175 mum) 1 year postoperatively. Best-corrected visual acuity significantly improved (preoperative mean +/- standard deviation [SD] value, 0.131 +/- 0.081 and 1 year postoperative mean +/- SD value, 0.407 +/- 0.193). Multifocal electroretinography values area 1 (0-2.8 degrees) and area 2 (2.8-9 degrees from the center of the fovea.) significantly improved (preoperative mean +/- SD values 3.10 +/- 1.334 nV/deg(2) and 3.573 +/- 1.545 nV/deg(2), respectively, and 1 year postoperative +/- SD mean values, 5.53 +/- 1.208 nV/deg(2) and 4.748 +/- 1.404 nV/deg(2), respectively). The thickness of the fovea, measured by OCT, significantly correlated with the BCVA 1 year postoperatively. One year postoperative MFERG values areas 1 and 2 were not correlated with 12,month BCVA and OCT findings. .CONCLUSIONS: Twelve months postoperatively BCVA and MFERG values significantly improved in this series of eyes with successful macular hole surgery. Optical coherence tomography findings were correlated to BCVA, but MFERG values were not correlated to BCVA and OCT findings, 1 year postoperatively. (C) 2002 by Elsevier Science Inc.

PURPOSE: To report optical coherence tomography (OCT) of retinal disorders in preeclampsia. DESIGN: Observational case report. METHODS: A 24-year-old woman developed hypertension (190/100 mm Hg), proteinuria, and generalized edema in the 34th week of pregnancy. Soon after undergoing a cesarean section, she noted severe impairment of vision in both eyes. RESULTS: Ten days after delivery, OCT showed a diffuse intraretinal edema that was still present but in a minor degree 2 months later. Eight months after delivery macular edema had resolved, but the highly reflective band of retinal pigment epithelium (RPE) and choriocapillaris was thickened with focal elevations corresponding to the Elschnig spots. CONCLUSION: In the acute phase of preeclampsia, OCT revealed a diffuse increase in macular thickness. Two months after delivery, macular edema still existed but in a minor degree. Eight months after the first examination, OCT depicted restoration of the contour of the fovea. Moreover, OCT showed the characteristic RPE focal elevations and abnormalities corresponding to the Elschnig spots.

We report the clinical and angiographic features as well as the natural course of an optic disk and juxtapapillary combined pigment epithelial and retinal hamartoma in a 23-year-old white girl. The patient presented 3 episodes of recurrent vitreous hemorrhages in the first 4 years of follow-up, which were spontaneously and totally absorbed. During the last 6 years, she was absolutely free of any ocular symptom. The tumor did not show any growth during the 10 years of follow-up. The digital indocyanine green angiography, which was normal in the early frames, revealed a mild, patchy hyperfluorescence corresponding to the tumor location in the Late phase. Copyright (C) 2001 S.

PURPOSE: To report optical coherence tomography in optic disk pit maculopathy treated with macular scleral buckling procedure. METHODS: Twenty six eyes (26 patients) with optic disk pit maculopathy were treated with macular buckling procedure and evaluated with optical coherence tomography. In group 1, five eyes were evaluated with optical coherence tomography before and after macular buckling procedure. In group 2, 21 eyes were evaluated with optical coherence tomography after macular buckling procedure. With optical coherence tomography, cross-sectional, horizontal retinal images were obtained through the fovea and optic disk pit. RESULTS: In group 1, four of five eyes showed absorption of intraretinal fluid 7 to 9 months after macular buckling procedure. After absorption of fluid, retinal thickness in the foveal center ranged from 128 to 178 mum. In one eye the channel from optic disk to fovea reopened and fluid reappeared. In group 2, 20 of 21 eyes showed absorption of intraretinal schisis and subretinal fluid after macular buckling procedure. After absorption of fluid, retinal thickness in the foveal center ranged from 119 to 216 mum. CONCLUSIONS: In optic disk pit maculopathy, optical coherence tomography enabled morphologic assessment of the retina before and after macular buckling procedure. In the successfully treated cases the permanent closure of the connection between the optic disk pit and the intraretinal schisis was demonstrated. Eventual dis, appearance of schisis and subretinal fluid was depicted. It was also proved that the thickness of the macula returned to normal and visual acuity improved.

Purpose: To investigate the hemostatic effects of SF6 gas in preventing post-operative vitreous hemorrhage in diabetic vitrectomy, Methods: A prospective, randomized study of 33 diabetic eyes with vitreous hemorrhage, treated by vitrectomy, In 17 of our cases SF6 20% was injected into the eye at the end of the operation, while in 16 cases BSS remained in the vitreous cavity, Results: The incidence of vitreous hemorrhage recurrence was 17.6% for the SF6 group and 12.5% for the BSS group (statistically not significant). Progression of lens opacities was observed in 23.5% of the SF6 group, and in 18.8% of the BSS group (statistically not significant, with a higher incidence in the SF6 group). Conclusions: SF6 gas did not show hemostatic effects in the cases studied. Furthermore, it may have contributed to cataract progression. Therefore we suggest that the use of SF6 is not recommended as a treatment modality in preventing new vitreous hemorrhage after diabetic vitrectomy.

PURPOSE: To report a case of Goldmann-Favre syndrome with special emphasis on the optical coherence tomography findings. METHODS: In a 23-year-old white man with an 8-year history of visual impairment in both eyes and night blindness, vertical and horizontal optical coherence tomography images were obtained through the macula and through the retinoschisis located at the temporal side of the macula. RESULTS: Optical coherence tomography showed in the left eye a clear loss of the inner retinal layer at the fovea and the formation of inner and outer retinal layer holes in the temporally located retinoschisis, The outer retinal layer hole had rolled edges. CONCLUSION: In Goldmann-Favre syndrome, optical coherence tomography demonstrated confluent macular cystoid changes and retinoschisis in both eyes. In the left eye, a lamellar macular hole and retinoschisis with inner retinal layer and outer retinal layer holes were observed. The outer retinal layer hole had rolled edges.

Purpose: To investigate the pattern of congenital optic disk pits associated with maculopathy using indocyanine green angiography (ICG) and fluorescein angiography (FA). Methods: Seventeen consecutive patients with unilateral congenital optic disk pit complicated by maculopathy were prospectively enrolled in the study. Complete ophthalmologic examination, color stereophotography, red-free photography, FA, and ICG angiography were performed on all patients during their first examination in our department. Results: Absolute hypofluorescence of the optic disk pit was noted in all eyes on ICG angiography. On the contrary, all eyes showed early hypofluorescence and late staining of the optic pit on FA. All 17 eyes presented a delineated late hyperfluorescence corresponding to the area of macular elevation on both ICG angiography and FA. The intensity of the hyperfluorescence was milder in cases with long-standing maculopathy. Conclusion: imaging of congenital optic disk pits associated or not with macular elevation using ICG angiography has not been reported in the literature. The increased hyperfluorescence in the late phases of the macular elevation in the studied eyes could be attributed to leakage of indocyanine or fluorescein dye into the schisis cavity and the subretinal fluid.

Purpose: To evaluate the presence and the evolution of cyst formation in optic disc pit maculopathy. Methods: In this prospective study, 18 cases with optic disc pit maculopathy were studied. Five of them showed cyst formation in the fovea at the initial examination. The fundus findings were documented with slit-lamp biomicroscopy, indirect ophthalmoscopy, and stereoscopic photography of the posterior pole. All 5 patients were treated with a macular scleral buckle procedure. Results: The presence of cysts in the elevated macula depends on the grade of the disease. Cyst formation can develop not only in the later stage of the disease but also quite early. In all 5 patients cyst formation gradually decreased and finally disappeared after the surgical procedure. Conclusions: Cyst formation is an entity which accompanies the macular detachment associated with optic disc pit. The development of the cysts has been noticed after the establishment of the schisis-like separation and before or in conjunction with the formation of a lamellar macular hole which usually accompanies the optic disc pit maculopathy.

Purpose: To evaluate visual field changes in 18 of 21 patients with unilateral optic disk pit maculopathy who were successfully treated with the macular buckling procedure. Methods: In this prospective study, visual field examination with the Humphrey analyzer (programs 30-2 and 10-2) was recorded before treatment, repeated 1 month after the operation, and repeated every 6 months thereafter. All 18 patients were treated with the macular buckling procedure. The operation consisted of fixation of a silastic sponge explant at the posterior pole corresponding to the macula. Results: In 18 eyes included in the study and successfully treated, an improvement in visual field indices was recorded. The mean deviation improved from -7.75 +/- 3.15 (program 30-2) and -10.19 +/- 3.66 (program 10-2) decibels before surgery to -6.25 +/- 2.61 (P < 0.0001) and -8.56 +/- 3.13 (P < 0.0001) decibels at the last examination, respectively. No additional visual field defect was induced in any of the 18 eyes after treatment. Also, the majority of the eyes (16/18) gained from 1 to 7 Snellen lines of visual acuity (P < 0.0001). Conclusion: Improvement of central and peripheral visual field (within 30 degrees of fixation) was recorded after the treatment of optic disk pit maculopathy with the macular buckling procedure. This technique seems to be effective for treatment of the disease with good anatomic and functional results.

Purpose: To describe a patient with acquired immunodeficiency syndrome (AIDS) who presented with cystoid macular edema (CME) which was not associated with active cytomegalovirus (CMV) retinitis or AIDS-related microvasculopathy. Method: A 32-year-old man with AIDS and a past ocular history of inactive CMV retinitis was placed on protease inhibitors when his CD4(+) T lymphocyte counts dropped to 8 cells/mm(3). Three months later, after his CD4(+) T lymphocyte counts had increased to 196 cells/mm(3) he complained of micropsia and metamorphopsia in his right eye of 1 week duration. The patient had a complete ocular examination including fluorescein angiography (FA). Results: Visual acuity (VA) was 7/10 OD. Fundus examination revealed CME and inactive CMV retinitis, and FA demonstrated CME and a hot disc. Two transseptal injections of corticosteroids were administered 2 weeks apart in the right eye as treatment of the CME. The patient reported gradual visual improvement and 6 weeks later, his VA was 10/10(-2). CME had resolved clinically and angiographically. Conclusions: CME in our case is associated with inactive CMV retinitis and gradually increasing number of CD4(+) T lymphocytes after initiation of treatment with protease inhibitors. It may be amenable to regional administration of corticosteroids without reactivation of retinitis.

PURPOSE: To report a rare case of ophthalmic dirofilariasis in a 68-year-old man with sudden, intense pain and itching in the left eye, The nematode was located in the eye and recognized as Dirofilaria repens. METHODS: Slit-lamp examination disclosed a moving nematelminth under the bulbar conjunctiva of the left eye, The nematode was surgically removed. RESULTS: The nematelminth surgically removed from the subconjunctival space was identified as D repens on the basis of transverse sections and its macroscopic characteristics. CONCLUSION: It is important to identify the nematode as D repens, based on both its microscopic and macroscopic characteristics, to avoid treatment with anthelminthic agents, The surgical removal of the worm is the sole recommended treatment.

Objective: To compare the efficacy and safety of topical 2.0% dorzolamide hydrochloride with oral acetazolamide in preventing intraocular pressure (IOP) rise following neodymium:YAG (Nd:YAG) laser posterior capsulotomy. Design: A prospective,randomized, double-masked, placebo-controlled study. Patients: Two hundred ten patients undergoing Nd: YAG laser posterior capsulotomy. Intervention: Pretreatment with dorzolamide, acetazolamide, or placebo. Dorzolamide administration as a single drop (1 drop approximate to 20 mu L) 1 hour before capsulotomy. Acetazolamide administration as a single dose of 125 mg orally 1 hour before capsulotomy. Results: At first and third hour postoperatively, IOPs and IOP changes from baseline were significantly (P.50) in the dorzolamide and acetazolamide groups. No patient treated with dorzolamide or acetazolamide experienced an IOP higher than 30 mm Hg after capsulotomy, but 15.7% of patients receiving placebo had an IOP above this level (P

PURPOSE: To evaluate the anatomic and functional outcome in nine patients with optic disk pit maculopathy after the use of the macular buckling procedure, METHODS: In this prospective study, nine consecutive patients (five women and four men with a mean age of 28 years [range, 14 to 49 years] who had unilateral maculopathy associated with optic disk pit) were treated with macular buckling surgery, A scleral sponge of 7.5 x 5.5 mm was fixed at the posterior pole of the globe corresponding to the macula along the vertical axis of the 12-to-6 o’clock meridian, No additional treatment of any kind (laser, diathermy, or cryotherapy) was used, The correct positioning of the sponge during the operation was monitored by B-scan ultrasonography, Within the first week after surgery, indocyanine green angiography was performed to evaluate the choroidal circulation. During the same period, magnetic resonance imaging of the orbit was performed to determine the sponge position in relation to the optic nerve, RESULTS: In all nine eyes, complete disappearance of subretinal and intraretinal fluid in the macula and in the surrounding area was noted, The absorption of the macular fluid started immediately after the operation and was completed after five to six months. No further change of the appearance of the fundus was noted during the follow-up period, which ranged from 18 to 66 months (mean follow-up, 42 months), Six eyes gained four or five lines of visual acuity, and two eyes improved by three lines, CONCLUSIONS: The macular scleral buckling procedure in optic disk pit maculopathy can yield favorable anatomic and functional results.

PURPOSE: We studied a case of congenital optic disk pit and coloboma with associated malformations of the retinal vessels. METHODS: Slit-lamp biomicroscopy and fluorescein angiography were performed. RESULTS: Multiple retinal venous anastomoses associated with a congenital coloboma and pit of the optic disk were observed. The retinal vascular anomalies extended from the optic disk to the temporal periphery. CONCLUSIONS: We consider the coexistence of retinal venous anastomoses with optic disk coloboma and pit to be an extremely rare congenital retinal anomaly.

Patients with beta-thalassemia may present with an acquired diffuse elastic tissue defect due to degeneration of elastic tissue along with vaso-occlusive findings in the retinal microvasculature. Here we report the case of a patient with granular-like accumulation presenting as black sunburst lesions detected by optical coherence tomography (OCT). A 38-year-old man with beta-thalassemia intermedia associated with angioid streaks complained of deterioration of vision in both eyes. Funduscopic examination revealed small, round, hyperpigmented lesions bilaterally. During the early and late phases of fluorescein angiography, granular hyperfluoresence was present, associated with pigment decompensation and mottled-like hypofluorescence. The main OCT finding was the presence of granuloid-like accumulations at the retinal pigment epithelium level. Granule penetration was also noticed at the photoreceptor layer, while isolated granuloid-like accumulations were found in the inner layers of the macula and choroid. In this case, the new OCT finding was the granular-like hyperpigmented accumulations in the macula located at the level of the retinal pigment epithelium. To the best of our knowledge, our OCT findings show for the first time granuloid-like accumulations representing black sunburst lesions.

Sixteen patients with large angle infantile esotropia with deviations of 80-90 prism dioptres were operated at the age of about 2 years. All patients underwent 8 mm bilateral medial rectus recessions. At the last follow up examination, 6 to 48 months postoperatively (average 16.3 months), successful horizontal alignment was achieved in 12 patients (75%). Four patients (25%) were undercorrected. Clinically significant limitation of adduction or convergence was not observed postoperatively in any of the patients. Consecutive exotropia was not encountered in this series but a longer follow up is probably needed in order to assess its delayed appearance. These results suggest that 8 mm recession of the medial recti is an effective procedure for the correction of large angle infantile esotropia of 80-90 prism dioptres and can be considered as an acceptable alternative to operations on three or four muscles.

We describe our technique and analyze the long-term results of the use of argon laser photocoagulation in the treatment of 92 eyes with recurrent trichiasis. In spite of an incidence of recurrences of 64.1% which had to undergo a new laser photocoagulation session, the final success rate of the method was impressive (91.3%). The number of misdirected cilia per lid seems to constitute an important factor which affects both the rate of recurrences and the success rate of the procedure.
