We present a case of Werner's syndrome (WS), which is a rare progressive hereditary disorder characterized by accelerated aging. Bilateral cataracts are one of the cardinal signs of WS. The clinical characteristics of our patient met the diagnostic criteria of “Probable WS” according to the International Registry of Werner Syndrome. Our patient presented with bilateral phacomorphic glaucoma. Previous reports involving single case of WS, cataract surgery was performed by clear corneal phacoemulsification. Our patient underwent immediate bilateral sequential manual small incision cataract surgery (IBSCS) with intraocular lens implantation. We highlight the fact that bilateral cataract surgery with Manual small incision cataract surgery (M-SICS) for phacomorphic glaucoma is a safe choice for patients with Werner's syndrome.

Werner's syndrome (WS) is a rare progressive genetic disorder. Unusually accelerated aging (progeria) characterizes WS, which is typically recognized by the third or fourth decades of life. Bilateral cataracts are one of the cardinal signs of WS. We report the successful management of a WS patient who presented with bilateral phacomorphic glaucoma.
| Case Report|| |
A 33-year-old patient presented with complaints of diminution of vision in both eyes for the past 15 days that was insidious in onset and painful in nature. The patient had associated mental retardation. The patient's height was 143 cm, and he weighed 30 kg. He had an “old man look,” with a bird-like face [Figure 1]a, pinched nose, alopecia; graying of beard; thin extremities with atrophied, hyperpigmented skin; decreased subcutaneous fat; and flat feet. He also had a high-pitched voice with a loss of dentition [Figure 1]b and [Figure 1]c. The patient had no family members with similar features and no history of consanguinity. Our patient met three cardinal and two additional signs from the diagnostic criteria suggested by International Registry of Werner Syndrome [Table 1]. Hence, we diagnosed this patient as “Probable WS.”

On ocular examination of both the eyes, it was found that his vision had light perception with accurate projection of light in both the eyes. The anterior segment examination showed bilateral circumciliary congestion with corneal edema and a shallow anterior chamber. The pupils were fixed, mid-dilated, and sluggishly reacting to light. In addition, the right eye also showed iris atrophic patches with posterior synechiae. Both eyes had intumescent mature cataracts with no view to the fundus [Figure 2]a and [Figure 2]b. Intra ocular pressure (IOP) by Goldmann Applanation Tonometer (GAT) in the right eye was 44 mmHg and left eye was 32 mmHg. No angle structures were visible on gonioscopy with four mirror Sussman gonioprism on indentation [Figure 2]c and [Figure 2]d.

On the basis of the ocular examination, a provisional diagnosis of bilateral phacomorphic glaucoma was made. The patient was admitted for treatment with a plan for cataract surgery with iol implantation once the cornea edema got resolved.
Preoperative preparation with intravenous injection of mannitol 20% w/v 100 ml was given over 45 min on admission and 1 h before surgery. Tablet acetazolamide 125 mg QID, tablet ranitidine 75 mg bis in die. Topical timolol eye drop continued BID.
The patient underwent immediate sequential bilateral cataract surgery (manual small incision cataract surgery) under general anesthesia with strict asepsis. The surgery protocols were derived from the previously published guidelines of the International Society of Bilateral Cataract Surgeons. Both eyes were operated by a single experienced surgeon in the same operation room. Utmost care was taken to maintain strict asepsis intraoperatively. Each eye was treated as a separate procedure with complete segregation of the two procedures. Both the surgeon and the assistant rescrubbed after completion of surgery in one eye. A new trolley with separate fresh autoclaved instruments, high molecular weight OVD (sodium hyaluronate 1.4%), irrigation line, and balanced salt solution was used.
Postoperatively the patient was put on moxifloxacin 0.5% eye drops six times per day for 2 weeks, prednisolone 1% eye drops every 1 h for the first day and then tapering doses for 1 month, and homatropine 2% eye drops thrice a day for 1 week, and timolol maleate 0.5% in both eyes.
Visual acuity on the first post-op day was 6/60 in his right eye and 6/36 in his left eye. The scleral tunnel wounds were well opposed [Figure 2]e and [Figure 2]f. Fundus of right eye had a 0.7:1 cup–disc ratio with inferior rim thinning and left eye with a 0.5:1 cup–disc ratio with a healthy neuro-retinal rim, mild pallor was present in both eyes, and macula was normal in both eyes [Figure 2]g and [Figure 2]h. On last follow-up of 3 months, the patient had a vision of 6/36 in right eye and 6/24 in left eye. IOP was 16 mmHg in the right eye and 13 mmHg in the left eye.
| Discussion|| |
WS is a rare, progressive hereditary disorder characterized by the appearance of unusual and accelerated aging. In most cases, the inheritance is autosomal recessive, but sporadic cases have also been reported. Although the disorder is typically recognized by the third or fourth decades of life, certain characteristic findings are present during adolescence and early adulthood. Affected individuals have short stature and low weight relative to height. By age 25, individuals with the disorder typically experience early graying and alopecia, as well as cataract develops at a relatively younger age in these patients.
It has a global incidence rate of less than 1 in 100,000 live births; only a handful of cases of WS have been reported till date. To the best of our knowledge, there is no existing literature on the safety of M-SICS in eyes with WS. We report the outcomes of M-SICS in eyes with WS presenting with phacomorphic glaucoma.
In previous case reports of WS, cataract surgery was done by clear corneal phacoemulsification and the corneal tunnel was sutured with nylon suture., Kusumesh et al. has reported a case of hypermature cataract successfully managed with clear corneal phacoemulsification. In our patient, the presence of intumescent lens made phacoemulsification challenging considering the associated risk of rhexis run away and intraoperative endothelial damage. In debilitated patients and special situations, requiring general anesthesia, immediate bilateral sequential manual small incision cataract surgery may be the ideal procedure.
In our case, M-SICS permitted a traumatic extraction of the nucleus with well apposed scleral tunnels and stable wound postoperatively, also there was no corneal edema suggestive of minimal intraoperative endothelial damage.
| Conclusion|| |
We highlight the fact that immediate sequential bilateral cataract surgery with M-SICS for phacomorphic glaucoma is a safe alternative for patients with WS.
