Clinical Case: A 63-year-old man presents with late hypotony maculopathy after non-penetrating deep sclerectomy. Hypotonia and visual acuity are improved after transconjunctival suturing of the scleral flap., Discussion: Hypotony maculopathy may occur as a late complication after glaucoma surgery. Transconjunctival suturing of the scleral flap can be useful when conservative measures have failed., (Copyright © 2018 Sociedad Española de Oftalmología. Publicado por Elsevier España, S.L.U.

Cyclodialysis is the result of the separation of the longitudinal fibres of the ciliary muscle from their scleral insertion, creating states of ocular hypotony. It is mainly caused by traumatisms. Gonioscopy has traditionally been the diagnostic test for this entity, however, at present it is being replaced by other techniques, such as ultrasound biomicroscopy (UBM). We present the case of a 57-year-old male who, following a traumatism in the left eye caused by the disc of a radial saw, presented corneal perforation and vitreous haemorrhage with pan-retinal edema. The gonioscopy was normal in spite of the existence of persistent ocular hypotony. The realization of a UBM enabled diagnosis of a small cyclodialysis of less than ten degrees. Surgical treatment made it possible to recover normal intraocular pressure.

Case Report: A 35-year-old man suffered a severe hipotension maculopathy after being kicked in his left eye. He presented a broad area of iridodialisis. Gonioscopy, ultrasound biomicroscopy and optic coherence tomography were not able to locate the suspected cyclodialysis. Medical treatment was ineffective. Five months later the patient received transcleral diode laser cyclophotocoagulation with clinical resolution., Discussion: Transscleral diode laser constitutes an effective treatment, with low iatrogenia, that can solve cases of ocular hypotension, even when the location of the cyclodialysis has not been determined., (Copyright © 2017 Sociedad Española de Oftalmología.

Purpose: To determine whether intravitreal injection of autologous plasmin enzyme (APE) is effective in vitreomacular traction syndrome (VMTS) by improving visual acuity and restoring macular morphology., Methods: A prospective study of 11 consecutive patients diagnosed with VMTS in the Ophthalmology Department from January to May, 2011., Inclusion Criteria: best corrected visual acuity (BCVA) less than 0.5, and vitreomacular attachment in foveal area resulting in macular thickness>250 microns diagnosed by optical coherence tomography (Cirrus OCT, Carl Zeiss Meditec, Inc, Oberkochen, Germany)., Exclusion Criteria: active proliferative diabetic retinopathy, axial myopia>26mm, vitrectomy, glaucoma, previous intravitreal injections and previous rhegmatogenous detachment. One to 3 monthly intravitreal injections of 0.2ml of APE were applied, interrupting if posterior vitreous detachment was attained. Wilcoxon's test was used for statistical analysis., Results: A total of 12 eyes of 11 patients were treated. A complete posterior vitreous detachment was achieved in 4 (33%) eyes at the end of the study, 2 of them with one injection, and 2 with 3 monthly injections. Improvement of BCVA was statistically significant (P=.017) and the decrease in central macular thickness also was statistically significant (P=.016). There was only one complication: intraocular hypertension after injection that subsided with a new paracentesis., Conclusions: Intravitreal APE injections avoided vitrectomy in VMTS in one in every 3 patients., (Copyright © 2011 Sociedad Española de Oftalmología.

Case Report: A 28-year-old man who received a blunt trauma in his left eye, presented with persistent ocular hypotony (intraocular pressure: 4 mmHg) as well as loss of visual acuity (0.4), optic disc edema and chorioretinal folds in the macula. The foveal thickness, measured by optic coherence tomography, was 326 microns. Using ultrasound biomicroscopy, a desinsertion of the nasal iris and a 360 degrees choroidal detachment was observed. The hypotony did not respond to conservative treatment and 10 months after the trauma he underwent a transscleral cyclopexy with contact diode laser. One year after the laser treatment the visual acuity was 1.0, the intraocular pressure 14 mmHg and the foveal thickness 240 microns., Discussion: Transscleral cyclopexy with diode laser may be an effective alternative treatment to resolve post-traumatic cyclodialysis that does not respond to medical treatment.

Case Reports: We report two cases of delayed spontaneous hypotony associated with choroidal detachment and hypotony maculopathy. Both patients had undergone uneventful cataract extractions 10 and 6 years prior to the occurrence of apparently spontaneous hypotony. Trabeculectomy was combined with phacoemulsification in one of them. Both had been receiving timolol at the time of presentation., Discussion: Delayed spontaneous hypotony, without recent ocular surgery or trauma, represented a challenge in both the diagnosis and management processes in these patients. We have analysed the main causes.

Case Report: A 35-year-old man with degenerative myopia suffered blunt ocular trauma due to being hit in the face by a ball. The injury caused four cyclodialysis clefts in his left eye which resulted in hypotony and chorioretinal folds., Discussion: The persisting hypotony was unsuccessfully treated with topical therapy and with laser photocoagulation. Therefore, a surgical treatment with direct cyclopexy was performed. In one of the cyclodialysis clefts, incarcerated vitreous was found, and this was considered to be the reason for its incomplete closure. In the postoperative period complete closure of the cyclodialysis cleft was observed; however an unexpected filtering bleb appeared, which could have affected good control of intraocular pressure.

Purpose: To analyze the anatomical and functional results obtained in post- surgical suprachoroidal hemorrhages treated from 1998 to 2000 and to review the information on the series of this complication that have been published during the last five years and which included at least 10 patients., Methods: A retrospective analysis of the medical records of patients with suprachoroidal hemorrhages at the Instituto Universitario de Oftalmobiología Aplicada (IOBA) - University Hospital of Valladolid. Bibliographic search by Med-Line/Pub Med from 1995 to 2000 was performed., Results: 8 patients who fulfill these criteria have been treated and 8 papers, also complying with the criteria, have been found., Conclusions: The functional and anatomic results of post-surgical suprachoroidal hemorrhages are still poor, even though the prognosis seems to have improved in the last 20 years. The standardized classification of massive suprachoroidal hemorrhages based on severity and the standardization of the follow-up would improve these results.
