MULTIMODAL IMAGING IN A CASE OF CENTRAL RETINAL ARTERY OCCLUSION IN THE PRESENCE OF TYPE 2 MACULAR TELANGIECTASIA.

PURPOSE: To report a case of central retinal artery occlusion in a patient with macular telangiectasia Type 2 using multimodal imaging. METHODS: Observational case report. RESULTS: A 58-year-old woman who presented with acute painless unilateral vision loss was diagnosed with central retinal artery occlusion in her right eye with macular telangiectasia Type 2 findings in both eyes. Fundus examination revealed retinal whitening with unusual cherry-red spot plus small crystalline deposits in the temporal macula. Surprisingly, spectral domain optical coherence tomography of the contralateral eye showed characteristically intraretinal hyporreflective spaces, whereas optical coherence tomography angiography exhibited microvascular abnormalities in the deep capillary plexus. At follow-up, a pseudolamellar macular hole was noticed in the affected eye with no recovery of best-corrected visual acuity. CONCLUSION: This case describes an onset of central artery occlusion in a patient with underlying macular telangiectasia Type 2 and suggests that it had a possible role in the acceleration of its natural course. The utility of multimodal imaging lies on better accuracy in diagnosis as well as prognosis, management, and monitoring of the disease.

Efficacy and safety of pop-titrated versus fixed-energy trans-scleral diode laser cyclophotocoagulation for refractory glaucoma.

PURPOSE: To compare the efficacy and safety of pop-titrated versus fixed-energy diode laser trans-scleral cyclophotocoagulation (DLTSC) for refractory glaucoma. METHODS: This is a prospective, interventional, longitudinal, and comparative case-control study. Patients with refractory glaucoma treated with pop-titrated DLTSC were compared to a fixed-energy DLTSC control group. Variables analyzed included: age, gender, diagnosis, pre- and post-treatment intraocular pressure (IOP). Success rate, anti-glaucoma medications reduction, and complications were analyzed at day 90 post-treatment. Primary success criterion consisted of eyes with a postoperative IOP ≤ 22 mmHg or a 30% reduction of pre-treatment IOP and managed with topical anti-glaucoma medications only. RESULTS: A total of 68 eyes from 67 patients were included for analysis: 30 in the pop-titrated group and 38 in the fixed-energy group. Therapeutic success was achieved in 56-72% of the pop-titrated group versus 47-52% in the fixed-energy group considering the 3 different criteria analyzed (p = 0.23-0.4). There was a 22% (from 4.1 to 3.2 drugs) reduction of anti-glaucoma medications in the pop-titrated group, compared to 32% (from 3.5 to 2.4 drugs) in the fixed-energy group (p = 0.42). Five eyes (13.1%) developed hypotony, all of which belonged to the fixed-energy group (p = 0.048). CONCLUSIONS: Pop-titrated DLTSC represents an effective and safe option for the management of refractory glaucoma. We found no statistically significant difference in success rates among both groups. However, there was a significantly higher risk of hypotony in eyes treated with the fixed-energy protocol.

Complete Vogt-Koyanagi-Harada disease and Holmes-Adie syndrome: case report.

We report a 37-year-old woman with uveitic phase of Vogt Koyanagi Harada disease and tonic pupil, the tonic pupil persisted after other clinical features of this syndrome had disappeared; neurological evaluation shows absent knee and arm tendon reflexes and positive cholinergic supersensitivity test with Pilocarpine 0.125% confirming the diagnosis of Holmes Adie Syndrome.
