Lesion Peeling and Phototherapeutic Keratectomy for Gelatinous Drop-Like Corneal Dystrophy
Purpose
To evaluate the effect of lesion peeling and Phototherapeutic Keratectomy (PTK) on the corneal structure and vision in patients with Gelatinous drop like corneal dystrophy (GDLD).
Methods
Retrospective, consecutive case series.
Three eyes of two patients with Gelatinous drop like corneal dystrophy underwent lesion peeling and PTK followed by Mitomycin C application. One patient with bilateral corneal affection also had Retinitis pigmentosa. Outcome measures included improvement in best spectacle corrected visual acuity (BSCVA) and ocular symptoms. Patients were followed up for 6 months.
Results
All 3 patients showed an improvement in visual acuity from a preoerative BSCVA of 20/400 in two eyes and 20/200 in one eye to a postoperative BSCVA of 20/100, 20/40 and 20/30 respectively. Ocular symptoms as foreign body sensation and photophobia improved.
Conclusion
Lesion peeling and PTK appears to be an effective method for the treatment of Gelatinous drop like corneal dystrophy.
