A Study of the Cataractogenic Potential of Seroquel and Risperdal in the Treatment of Participants With Schizophrenia or Schizoaffective Disorder

Presence of C type of cataractogenic potential event in participant was defined if any LOCS II grades of 2, 3, 4, 5 (with any grade of 0, trace,1 at randomization) assessed and agreed by 2 independent, treatment-masked ophthalmologists at any post-randomization assessment in one or both eyes. 0= no cataract; 5 is worst. There are no subscales. 0 is the best, 5 is the worst.

Presence of N type of cataractogenic potential event in Participants was defined if any LOCS II grades of 2, 3, 4 (with grade at rand equals 0,1), or if the LOCS II grades of 3,or 4 (with grade at randomization=2) assessed and agreed by 2 independent, treatment-masked ophthalmologists at any post-randomization assessment in one or both eyes. 0 is the best, 4 is the worst.

Presence of P type of cataractogenic potential event in participant was defined if any LOCS II grades of 1, 2, 3 , 4 (with grade=0 at randomization) assessed and agreed by 2 independent, treatment-masked ophthalmologists at any post-randomization assessment in one or both eyes. 0 is the best, 4 is the worst.

PANSS total score equals sum of the 30-items scores (range: 30-210). Each item has ( 1-7 units), 1 indicates "absent" psychosis symptom, and 7 - "extreme" symptom degree. Change in PANSS total score : total score at month 24 minus total score at randomization.Alleviation of psychotic symptoms are indicated by a negative change in PANSS total score.

PANSS Positive subscale score equals sum of the 7-items scores(range:7-49). Each item has ( 1-7 units), 1 indicates "absent" psychosis symptom, and 7 - "extreme" symptom degree.

PANSS Negative subscale score equals sum of the 7-items scores(range:7-49). Each item has ( 1-7 units), 1 indicates "absent" psychosis symptom, and 7 - "extreme" symptom degree. Change in PANSS Negative subscale score:score at month 24 minus score at randomization. Alleviation of negative psychotic symptoms are indicated by a negative change score.

PANSS psychopathology subscale score equals sum of the 16-items scores(range:16-112). Each item has ( 1-7 units),1= "absent" psychosis symptom, 7= "extreme" symptom degree.Change in PANSS psychopathology subscale:score at month 24 minus score at randomization. Alleviation of general psychopathology symptoms are indicated by a negative change score.

CGI-S score is accessed on a seven-graded scale ranging from most extremely ill/ very much worse (7) to normal/very much improved (1) , 1 is best. Change : score at month 24 minus score at randomization.

Q-LES-Q total score is the sum of the 16 times of Q-LES-Q SF(range:16-80).Each item has a 5 point satisfaction level scale:from 1=very poor(worst value) to 5=very good(best).Larger values indicate a higher perceived quality of life enjoyment and satisfaction.Change in Q-LES-Q total score:total score at month 24 minus total score at randomization

PETiT total score is the sum of the 30 items of PETiT questionnaire(range:0-60) on subjects perceived well-being, adherence, tolerability, satisfaction with treatment. Each item is rated by participant with a 3 point frequency scale:2=often, 1=sometimes, 0=never.Change in PETiT total score: total score at month 24 minus total score at randomization

Relapse is defined as a hospital stay for psychiatric symptoms or a 2-point increase from baseline in the CGI severity score. CGI-S score ranges from 0-7 with 0 = Not Assessed, 1 = Normal, not at all and 7 = Among the most extremely ill subjects.

SAS total score is the sum of the 10 individual-item scores (range:0-40), with the score for each item ranging from 0 to 4, higher scores indicate greater severity of Parkinsonian symptoms. Change : total score at month 24 minus total score at randomization. Increase in Change of total score indicates an increase in extrapyramidal motor symptoms.

BARS global score is the 4th individual-item score on the BARS scale, the Global Assessment of Akathisia, with the score ranging from 0 (no evidence of akathisia) to 5 (severe akathisia). Change : score at month 24 minus score at randomization. Increase in Change of BARS global score indicates an increase in akathisia.

AIMS total score is the sum of the 10 individual-item scores(range:0-40), with the score for each item ranging from 0 to 4. Change : total score at month 24 minus total score at randomization. Increase in Change of total score indicates an increase in abnormal voluntary movements. The lower score means lower intensity of abnormal voluntary Movements. 0 is best, 4 is worst. Increase in Change of total score indicates an increase in abnormal voluntary Movements.

Number of participants with adverse events potentially associated with EPS collected by MedDRA Preferred Terms as akathisia, bradykinesia, drooling, dyskinesia, dystonia, extrapyramidal disorder, grimacing, muscle rigidity, parkinsonism, restlessness, tardive dyskinesia, tremor
