Dear Editor,

Macular edema can occur in a large variety of ocular diseases.[1] Several treatment options such as oral and topical therapy, lasers and vitreous surgery by various mechanisms help in the resolution of macular edema.[1] Recently, intravitreal Triamcinolone Acetonide has been used to treat refractory macular edema with encouraging results.[2],[3]

This communication elucidates the efficacy of intravitreal Triamcinolone Acetonide to treat refractory macular edema in an eye that had undergone vitreous surgery to manage infectious endophthalmitis. A 53-year-old man presented with infectious endophthalmitis following phacoemulsification and intraocular lens implantation. He had already received two intravitreal injections by the treating physician elsewhere but no details were available. His visual acuity was bare light perception. After comprehensive examination, he underwent parsplana vitrectomy with removal of intraocular lens. At the time of vitrectomy vancomycin 1 mg/0.1 ml, ceftazidime 2.25 mg/0.1 ml and dexamethasone 400 micrograms were given. Pseudomonas aeruginosa was isolated in the culture. Sensitivity pattern showed susceptibility to ceftazidime. Systemic ceftazidime was started and intravitreal dosage repeated. Oral and topical steroids were also started. In addition, topical medications of ceftazidime, ciprofloxacin and tobramycin were used.

Three months after surgery, vision was 20/30 with no evidence of intraocular inflammation. A month and a half later, he noticed decreased vision. Fundus examination showed mild vitreous turbidity and few superficial hemorrhages in peripapillary area; visual acuity was 20/120 [Figure - 1]. Since there were clinically no signs of infection in the form of anterior chamber reaction/ hypopyon/ vitritis, it wasn't considered to be due to an infective etiology and hence no additional investigations were done. Fundus fluorescein angiography showed leakage from perifoveal network and disc capillaries [Figure - 2]. Optical coherence tomography (OCT) showed increased retinal thickness and cystoid changes in macula [Figure - 3].

As conservative treatment, ketorolac tromethamine 0.5% eye drops and prednisolone acetate 1% eye drops were prescribed four times per day for one month, without improvement. A month later, intravitreal Triamcinolone Acetonide was injected. A month later, visual acuity remained 20/120; however OCT showed good resolution of macular thickness [Figure - 4]. Nine months later, visual acuity improved to 20/60 with no evidence of recurrence of macular edema [Figure - 5] or inflammation.

While indications of use of Triamcinolone are expanding, its role in resolving macular edema in eyes that underwent vitreous surgery for infectious endophthalmitis has not been reported. In the present report, despite the highly virulent organism responsible for acute endophthalmitis, the eye responded well. This is supported by the complete anatomic and to some extent functional recovery, substantiated and quantified by OCT, as in other causes of macular edema by other case series.[4] In the present report, the eye responded quite well to vitreous surgery with improvement of vision to 20/30. However, the recurrence of inflammation along with refractory macular edema caused decreased vision. Intravitreal Triamcinolone Acetonide not only helped in resolving the macular edema, but also in improving vision. Hence, it is worth evaluating the role of peroperative Triamcinolone injection in eyes with infectious or inflammatory etiology.[5]
