Subthreshold laser treatment for non-center involved diabetic macular edema via non-damaging retinal laser therapy (NRT).

PURPOSE: To evaluate the efficacy of subthreshold laser treatment via non-damaging retinal laser therapy (NRT) in patients with non-center involved diabetic macular edema (non-CI DME). METHODS: In this prospective controlled study, NRT with 577 nm wavelength was performed to the edematous inner subfields as needed at 3 monthly intervals, while the control group received no treatment. If CI-DME developed in either group, intravitreal anti-VEGF was performed and the eye was excluded from subsequent analysis. RESULTS: A total of 75 eyes (36 study eyes, 39 controls) were evaluated. The change in superior, nasal and temporal inner subfield thicknesses over time and between groups was found significant (P = 0.004, P < 0.001, P = 0.04 respectively). Best corrected visual acuity (BCVA) change was not significant over time and between groups (P = 0.69). Rates of CI-DME development requiring intravitreal anti-VEGF treatment were not different during the first and second years (P = 0.171, 0.908). No laser scar was detected in any eye in fundus autofluorescence imaging. CONCLUSION: NRT performed as needed at 3 monthly intervals is effective after 21 months of follow up in the treatment of non-CI DME and it was safe. With this method, it may be foreseen that BCVA will be better preserved in the long term by avoiding the possible side effects of conventional laser.

Consequences of Real-World Surveillance of Fellow Eyes in Neovascular Age-Related Macular Degeneration.

This study investigated whether the interval of monitoring at-risk, fellow eyes of patients with unilateral neovascular age-related macular degeneration (nAMD) has any bearing on the severity of the disease at the time of diagnosis. The study comprised a retrospective, cross-sectional comparative case series of treatment-naïve eyes in patients who were diagnosed sequentially with nAMD. We compared the visual acuity (VA) and central macular thickness (CMT) of patients who were actively receiving intravitreal injections (IVIs) of anti-vascular endothelial growth factor (anti-VEGF) agents at the time of second eye diagnosis with the VA and CMT of patients who had ceased treatment in their first eye because of reaching end-stages of disease. Intervals of visits and frequency of monitoring the macula of fellow eyes by means of optical coherence tomography (OCT) were abstracted from the medical record. We found that the at-risk fellow eyes of patients who had stopped treatment for nAMD in their first eye prior to fellow eye conversion were monitored significantly less frequently than the fellow eyes of patients who continued to receive treatment at the time of second eye diagnosis. Despite less frequent monitoring, VA and CMT were similar at the time of fellow eye diagnosis for both groups.

SPONTANEOUS SUPRACHOROIDAL HEMORRHAGE ASSOCIATED WITH IATROGENIC COAGULOPATHY.

PURPOSE: To present a case of spontaneous suprachoroidal hemorrhage in a patient on anticoagulation. METHODS: Single case report. RESULTS: A 68-year-old woman with a history of hypertension, atherosclerosis, and heart failure presented with massive spontaneous suprachoroidal hemorrhage in the left eye. She had no known ophthalmic pathology. She was taking warfarin and she had a high international normalization ratio. Despite medical and surgical therapy, there was no improvement and vision deteriorated to no light perception. CONCLUSION: Spontaneous expulsive suprachoroidal hemorrhage is a rare entity. Advanced age, systemic anticoagulation, and hypertension are strong risk factors. It is important to monitor international normalization ratio in warfarinized patients; particularly, uncontrolled high levels may cause spontaneous suprachoroidal hemorrhage in the absence of predisposing ocular pathology.
