Methods:

Forty-five patients with pseudophakic retinal detachment were analyzed retrospectively. Patients with a final visual acuity greater than 0,1 (snellen equivalent) were defined as having a good visual prognosis. Parameters examined were age, gender, duration of the symptoms, preoperative visual acuity, preoperative intraocular pressure, macular status, redetachment rate and role of scleral buckling.

Effectiveness / Safety:

Mean age of patients was 60,50±11,1 and mean follow-up period was 18,7±8,7 months. Visual acuity improved from 2,5 ±1,03 (logMar) preoperatively to 0,7±0,6 (logMar) postoperatively (p=0.00). Mean preoperative intraocular pressure (IOP) was 12,64±3,40mmHg and mean postoperative IOP was 14,40±2,58mmHg. Macula-off retinal detachments were present in 14 (31,1%) patients; redetachment was detected in 11 patients (24,4%). Fifteen (33,3%) patients underwent scleral buckling with PPV. While age, gender, preoperative IOP, macular status, duration of symptoms, recurrence rate and scleral buckling were recorded as insignificant prognostic factors, there was a statistically significant relationship between preoperative visual acuity and postoperative functional success (p=0,02). Patients with a final visual acuity greater than 0,1 snellen lines had better preoperative function.

Take home message:

Preoperative visual acuity proved to be a significant prognstic factor for postoperative visual improvement after 23-G vitrectomy in pseudophakic retinal detachment.
