CLINICAL AND STRUCTURAL IMPACT OF SUBMACULAR FLUID AFTER PNEUMATIC RETINOPEXY REPAIR FOR RHEGMATOGENOUS RETINAL DETACHMENT

imagePurpose:

To assess the impact of submacular fluid (SMF) after pneumatic retinopexy for primary rhegmatogenous retinal detachment repair.

Methods:

Retrospective review of consecutive patients treated with pneumatic retinopexy for primary rhegmatogenous retinal detachment repair. 387 eyes (374 patients) were included, of which 166 underwent optical coherence tomography imaging after successful pneumatic retinopexy. Foveal-centered optical coherence tomography scans were reviewed.

Results:

SMF occurred in 59 eyes (35.5%) and was associated with macular detachment (P ≤ 0.001) and phakic lens status (P = 0.007). Submacular fluid resolved over an average of 9.39 months and was associated with worse preprocedure best-corrected visual acuity and delayed visual recovery. The mean final best-corrected visual acuity was 0.277 logarithm of the minimum angle of resolution (20/40) in eyes with SMF and 0.162 logarithm of the minimum angle of resolution (20/30) in those without SMF (P

COMPARISON OF AIR VERSUS PERFLUOROPROPANE INTRAOCULAR TAMPONADE COMBINED WITH VITRECTOMY FOR THE TREATMENT OF MACULAR HOLE IN HIGH MYOPIA

imagePurpose:

To compare the efficacy of air and perfluoropropane (C3F8) with pars plana vitrectomy (PPV) in highly myopic macular holes (HMMHs) and explore the factors related to surgical prognosis.

Methods:

A retrospective comparison of a consecutive series of HMMHs undergone vitrectomy and internal limiting membrane peeling. According to tamponade type, they were divided into air group and C3F8 group, which were further divided into subgroups based on hole diameter or axial length (AXL). Anatomical and functional outcomes were compared between tamponades. Related factors of initial closure rate and postoperative best-corrected visual acuity (BCVA) were analyzed by logistic regression.

Results:

The baseline characteristics in air group (n = 63) and C3F8 group (n = 37) were similar except the age of air was older (P = 0.019). The mean follow-up period was 17.16 ± 17.97 months. After surgery, the initial closure rate of air group was 85.7% and that of C3F8 group was 83.7% (P = 0.780). And the initial closure rate showed no difference between tamponades in the same subgroup classified by hole diameter or AXL (all P > 0.05). Postoperative BCVA improved significantly in both groups (P
