Long-Standing Macula-Involving Diabetic Tractional Retinal Detachments with Good Visual Acuity: How Should We Manage...

Area of Science:

• Ophthalmology
• Retinal Surgery
• Diabetic Retinopathy Management

Background:

• Chronic macula-involving tractional retinal detachment (TRD) in proliferative diabetic retinopathy (PDR) presents a surgical challenge.
• Pars plana vitrectomy (PPV) is a common surgical intervention for retinal detachment.

Purpose of the Study:

• To evaluate the efficacy of pars plana vitrectomy (PPV) in patients with good visual acuity and chronic macula-involving TRD secondary to PDR.
• To compare outcomes between prompt PPV and deferred treatment for this condition.

Main Methods:

• Retrospective review of medical records for 58 patients with PDR-associated macula-involving TRD (>6 months duration) and baseline visual acuity (VA) of ≥20/50.
• Patients were divided into a Study Group (prompt PPV) and a Control Group (deferred PPV).
• Minimum follow-up of 12 months, with an average follow-up of 27.6 months.

Main Results:

• Both groups experienced similar overall vision loss (-0.30 ±0.52 logMAR).
• Rates of maintaining ≥20/200 and ≥20/50 VA were comparable between the prompt PPV and deferred treatment groups.
• The prompt PPV group demonstrated a significantly higher likelihood of gaining ≥2 lines of VA (p=0.002).

Conclusions:

• Prompt pars plana vitrectomy (PPV) in patients with good visual acuity and chronic macula-involving tractional retinal detachment (TRD) secondary to proliferative diabetic retinopathy (PDR) is associated with a greater chance of significant visual improvement.
• While overall vision loss may be similar, early surgical intervention appears beneficial for a subset of patients.
